The objective of this research was to evaluate intercropping systems with maize and Brachiaria decumbens and your effects on the cultures mineral nutrition. The experiment was conducted in 2005, in the experimental area of "Campus Delza Gitaí" belonging to the "CECA - UFAL". The treatments consisted of a BRS 3150 hybrid of maize, cultivated in the systems: Conventional Cropping, Minimum Cultivation and No-tillage (BRS 3150 intercropped with Brachiaria decumbens), the randomized block design was used, with subdivided splots and four replications. During maize flowering period leaves from the ear basis were collected for nutritional analysis. Samples of Brachiaria decumbens to evaluate dry matter accumulation were collected in four different times, the third collection of plant matter was used for nutritional analysis. The results analysis allowed concluding that the use of Brachiaria decumbens did not influence in maize mineral nutrition; the residual effect of fertilizer applied to maize favoured the Brachiaria decumbens increaseing your nutritive value; the Brachiaria decumbens had your growth limited when it was cultivated in intercropping due the shading effect occasioned for maize.
